Abstract

Polymer Matrix Composite (PMC) is a composite material that uses a polymer matrix most widely used in industry, transportation, and everyday life. Plywood is one of the current industrial needs that is growing rapidly and is becoming a leading export. However, besides that, the availability of raw materials is decreasing along with deforestation. Resulting in the need for alternative raw materials. Straw is one of the largest wastes that is not utilized optimally. It can be used as straw as a reinforcing material for environmentally friendly composite materials. Composite material was made using the hand lay up method, with straw fiber purchased with 4% NaOH treatment using Yukalac 157 BQTN-EX unsaturated polyester resin and MEPOXE A hardener. Then, tensile testing was carried out with volume fractions of straw fiber 5%, 10% 20% and 30 % This shows that the volume fraction of straw fiber affects the strength of the composite material. The tensile strength value of the straw fiber composite meets the minimum standard for tensile strength in plywood. Judging from the surface structure of the composite material, there are voids or air bubbles. However, the most visible in the sample with fractions of 10% and 20%. Further research needs to be done with other tests such as hit test, sandpaper test to meet the requirements for SNI standard plywood.

Abstract

The manufacturing industry is currently experiencing rapid development from various aspects. This aspect develops, it is increasingly necessary to find solutions to get more effective and efficient results. The Air Handling Unit (AHU) machine is a heat exchanger between cold water and air. The method used to identify the damage is the Failure Mode and Effect Analysis (FMEA) method. With this method, it is hoped that the point of damage that occurs can be known and can be planned for further maintenance. The results of the analysis of the FMEA method were obtained from related fields regarding the damage to the AHU engine components. Based on the results of the analysis of the Pareto diagram, it can be seen that there are several types of damage that dominant in the Air Handling Unit engine, namely; Motors & blowers; Pipe; Air Filter; Spray Nozzles. According to the principle of the Pareto diagram, which is 80/20, it means that 80% of damage to the machine is caused by 20% of the causes of damage. In this case damage the motor & blower, pipelines, air filters must be prioritized for maintenance so that the quality and efficiency of the engine is getting better.

Abstract

Indonesia merupakan negara kepulauan dengan potensi laut yang besar. Hal ini membuat Indonesia memiliki potensi produksi akuakultur terbesar di dunia. Tantangan besar akuakultur yaitu cara meningkatkan produktivitas untuk suplai pangan, namun dengan penggunaan sumber air dan lahan yang lebih efisien. Hal tersebut tentu perlu didukung oleh pengembangan teknologi yang hemat energi serta kualitas air yang tetap terjaga pada kondisi ideal. Pada sektor perikanan, kualitas air merupakan faktor utama untuk perkembangan budidaya ikan. Penelitian ini mengkaji kapabilitas dari Microbubble Generator (MBG) tipe orifice dengan pipa porous pada aerasi kolam ikan. Nilai Dissolved Oxygen/DO merupakan indikator kerja yang digunakan untuk menguji kapabilitas MBG. Pada penelitian ini diperoleh alat uji MBG tipe orifice dengan pipa porous berdimensi overall 0,5m x 0,5m x 1,5m, diameter lubang porous 0,3mm, diameter nozzle 20mm, pipa ¾ inch PVC, kapasitas aliran 430liter/menit, head tekanan 18m. Hasil pengujian pada ukuran kolam ikan 10m x 2,3m x 1m (tinggi air 85cm) dengan air standar (tanpa ikan), untuk setiap kedalaman (30cm dan 60cm) peningkatan harga DO sebanding dengan peningkatan diameter orifice. Pengaruh jarak semburan terhadap harga DO adalah berbanding terbalik, semakin jauh jarak semburan akan menurunkan harga DO. Pada variasi kedalaman, harga DO berada pada kisaran harga yang sama yaitu 8,15 ppm sampai dengan 8,16 ppm, hal ini menunjukkan bahwa pengaruh kedalaman tidak menunjukkan perbedaan harga DO yang cukup besar. Harga DO yang terukur dari hasil pengujian dengan variasi orifice dan kedalaman adalah cukup sesuai untuk aerasi kolam ikan, karena harga DO untuk air dengan ikan sekitar 2-4 ppm.

Abstract

Advances in science and technology in the industrial world today have resulted in the increasing need for materials for the ingredients of a product. Therefore, many new types of materials have been developed that resemble the properties of metals that can absorb or have high strength, such as old composite materials. Composite material is an alloy of two or more materials that have strong mechanical properties from the constituent materials. Composites consist of two main parts, namely the matrix as a binder and filler as a filler of the composite. One of the natural fibers that can be used as reinforcement for composites is pineapple leaf fiber and banana leaf fiber. The matrix used is polyester resin, the composite is made using the ASTM D 638 standard. This study aims to determine the effect of the ratio of fiber volume fractions on the composite of pineapple leaf fiber and banana midrib fiber in order to produce a high performance material. The results of mechanical testing in the tensile test of the composite have the greatest tensile strength and modulus of elasticity at the composition of 15% pineapple leaf fiber and 15% banana midrib fiber, which is 43.25 MPa tensile strength and 2.12 GPa modulus of elasticity. And the largest strain is in the composition of 5% pineapple leaf fiber and 5% banana midrib fiber, which is 4.21%.
